1 Internal MAP Water/Methanol Injection Controller , WARNING: Improper installation and/or adjustment of this product can result in major engine/vehicle damage! Use of this injection system requires proper tuning! Use this system with EXTREME caution! If you are! uncomfortable with anything about this, please refer the installation to an AEM trained tuning shop or call for technical assistance. You should also visit the AEM Performance Electronics Forum at NOTE: AEM holds no responsibility for any engine damage that results from the misuse of this product! This product is legal in California for racing vehicles only and should never be used upon a highway. This product is legal solely for vehicles used in competition which may never be used upon a public road or highway.

2 Controller Settings The AEM Water Methanol Injection Controller is a progressive type controller. This means that fluid will be injected in proportion to the amount of boost that is detected by the internal MAP sensor. In other words, more boost equals more fluid. It is therefore imperative that the vacuum/pressure connection be made properly and securely or vehicle/engine damage could occur. In addition, the controller will automatically compensate for any fluctuations in battery voltage variations to ensure consistent flow under all conditions. The two knobs on the face of the controller dictate at what manifold (boost) pressure minimum fluid injection starts and at what pressure maximum/full fluid injection occurs. Fluid injection will progressively increase between these two points as set by the adjustment knobs. The Start PSI dial has a range from 1 psig (full counterclockwise rotation) to 11 psig (full clockwise rotation). The Full PSI dial has a range of 5 psig (full counterclockwise rotation) to 35 psig (full clockwise rotation). It is suggested to adjust the Start PSI value by setting the dial to approximately 25% of the vehicles maximum boost. Adjust the full-in value to your maximum possible boost. These are only suggestions; improper use or setting could result in engine or vehicle damage -- please consult your tuner. Status LED The controller has an on-board Status LED. This will mimic the operation of the external LED. Upon startup the current mode is flashed in green on the status LED. It will flash error codes in red as well as illuminate with varying intensity as a function of flow in green. Fuse The controller has an externally accessible fuse. The controller itself will turn on and function, but the pump will not run without the fuse. If the controller is reporting an open circuit it may be that the fuse has blown, and or is not installed correctly. Use a 15 amp fast blow fuse for replacement purposes. Page 2

3 Test Button The Test button feature is available to test the systems functionality. This feature should be used ONLY with the nozzle disconnected from the engine. This is to prevent unintentional pumping of fluid into the engine. To operate the test button press and hold. The pump speed will gradually increase from zero to full speed over 3 seconds, and then remain full for another 3 seconds before stopping. Flow should begin gradually and then hold at full pressure for a total test time of 6 seconds. Short circuit self-diagnostics There are two modes of pump-driver short circuit protection available. One can detect a short at any time but produces a slight buzzing in the pump. This should not be noticeable under most conditions, but can be turned off if it is objectionable. If turned off, a short circuit can only be detected when the pump is running. To enable or disable this diagnostic (and the buzzing): Press and hold the Test button while applying power to the controller. The change is acknowledged by a single long flash of the status LED output and the external LED. Once the button is released the controller will continue to function normally. You can also tell what mode has been selected by listening for the buzzing sound in the pump. Repeating this operation will toggle between the two modes. Page 3

4 Controller Install The progressive controller is NOT waterproof and should NOT be mounted in the engine bay! Find a convenient location for the controller inside the driver s compartment. The adjustment knobs should remain in an accessible location but still remain protected from possible water incursion. If you need to extend the wires to mount the controller use at least wire for the pump and controller ground circuits and 18 for the remainder. The controller contains an externally accessible fuse, no additional fuses are required. Use the supplied zip-ties to mount the controller.

Grounded when error condition exists. Connect to the positive (red) wire of pump. Main ground connection, connect directly to battery ground. Connect to the white wire of the fluid tank level sensor* Connect to the black wire of the fluid tank level sensor* Arms injection system. Connect to a switched 12V source. Main Power Connection, connect directly to positive battery terminal. *Note: If fluid tank is equipped with previous generation level sensor, identified by having two black wires, then pins 8 (white) and 9 (brown) may be connected to either of the two black sensor wires. The polarity is unimportant. **Note: If you need to extend the wires to mount the controller use at least wire for the pump and controller ground circuits and 18 for the remainder. External LED Install Find a suitable location in the driver s line of sight to mount the external LED. Mount the LED and run the wires to the controller. The LED indicates the operation of the controller. If the pump is off and there are no errors the LED will be off. If there are no errors and the pump is on the LED intensity will vary with the pump speed. If there are any errors they will be indicated by flashing the LED. Boost Pressure Hose Using the supplied vacuum tee and rubber hose, tap into a manifold pressure (vacuum/boost) line. Page 4

5 Optional System Upgrades Water/Methanol Injection FAILSAFE Device AEM P/N 30-30/30-30M Actively monitors the entire flow curve independent of pressure, continuously collecting flow vs. injection rate data so that any deviation from your established flow curve will trigger an alarm output that can be used to reduce boost or timing, change maps, add fuel, trigger a two-step or perform practically any action you choose to save your engine. It is PC programmable (with USB connectivity) which eliminates the guesswork when setting min/max threshold parameters. HIGHLY RECOMMENDED for all water/methanol injection systems Water/Methanol Injection Flow Gauge AEM P/N / Displays flow rate data on a smooth moving needle-type gauge that allows you to accurately monitor the status of your injection system in real time. Available in max flow rates of 500 cc/min or 1000 cc/min with a black or white face. The AEM water/methanol injection filter is HIGHLY RECOMMENDED when using this flow gauge. Water/Methanol Injection Filter AEM P/N Inline filter that uses a micronic mesh screen to filter out particles as small as 40 microns. Allows a cleaner flow of water/methanol into the injection pump, lines, and nozzles increasing overall system longevity. Injection filter is HIGHLY RECOMMENDED when using the AEM water/methanol injection flow gauge. Additional Nozzle Kit AEM P/N Includes one nozzle body, two jet sizes, and the necessary hardware to run a second nozzle in your injection system. 5 Gallon Tank AEM P/N Upgrade to a 5 gallon tank to maximize your fluid holding capacity. Includes level sensor and mounting hardware. Page 5
